Exposure to Ethylene Oxide and Relative Rates of Female Breast Cancer Mortality: 62 Years of Follow-Up in a Large US Occupational Cohort

This updated analysis of an EtO-exposed worker cohort builds on evidence that EtO is a human breast carcinogen and supports recent exposure reduction proposals. Given the high prevalence of breast cancer, the large number of workers exposed to EtO and the potential for widespread environmental exposure increased risks observed even in the low exposure range are of serious public health importance. https://doi.org/10.1289/EHP15566.
